Before experimental drugs can be brought to market, they must undergo many rigorous trials to ensure they deliver their medical

benefits effectively and safely. One method commonly used in this process is to compare the effect of a drug with that of a placebo in double-blind tests. Which of the following correctly describes a double-blind test?
a. The researchers apply two-layered blindfolds to the study participants so that they cannot see whether they are receiving the drug or a placebo.
b. Neither the researchers nor the study participants know who is receiving the drug and who is receiving the placebo.
c. The researchers know who is receiving the drug and who is receiving the placebo, but they do not know what the supposed effects of the drug should be.
d. The researchers do not know who receives the drug or the placebo, but the participants know and tell them later.
e. None of the above is correct.

Answer:

b. Neither the researchers nor the study participants know who is receiving the drug and who is receiving the placebo.

Explanation:

In a double-blind test, there are two groups of participants: (1) people who are receiving the new drug and (2) people who are taking a placebo. Neither people from group (1) nor people from group (2) know what they are taking. Also, researchers recollect data from theses groups without knowing which person belongs to each group to avoid any "favoritism" caused by expected results.

belka [17]
It is crucial that we protect, conserve, and support the global population of producers. This claim is supported by the evidence that was discovered in the experiment of the water tank. As seen in the experiment, when the fish were increase, the levels of oxygen were decreased. Then, as soon as more plants (producers) were added to the tank, the oxygen levels increased once again. Theses evidences can be applied on a larger scale of the earth. An analogy could be made between the fish and plants in the tank to the animals, humans, and plants all over the world. As the population of animals and humans continue to grow around the world, more and more trees and plants get cut down. As this continues the oxygen levels will decrease, which can be supported by the evidence in the lab.
